Sensors for peripheral signal recordings in the lab environment

Brain Products has developed and offers a large variety of sensors. All of them are manufactured to meet the highest safety standards and are powered directly from the electrically isolated amplifiers. 

3D Acceleration Sensor

The 3D Accelaration Sensor captures movements in three dimensions. Its primary application is to detect and record movement/acceleration of the extremities. It consists of the sensor (2 sensors with cables of different lengths are supplied) and a pre-amplifier.

Blood Pulse Sensor

The Blood Pulse Sensor records the pulse wave by sending IR light through the finger and recording the light emitted by the oxygenated haemoglobin with a photo diode at the opposite side. It consists of a finger-clip sensor as well as an amplifier box and connects to the EEG amplifier via an auxiliary port.

GSR Sensor

The GSR Sensor measures skin conductance (SC) – a parameter for emotional and cognitive states, stress and pain. It uses the exosomatic recording principle with direct current (DC). This means that a constant voltage of 0.5 V is applied in order to acquire the skin conductance. The sensor consists of 2 surface electrodes and a GSR module, that converts the electric SC to a voltage recorded by a bipolar amplifier input. A GSR-specific gel (Edalyt) is also supplied.

Photo Sensor

The Photo Sensor provides information on the brightness of the screen, i.e. the signal delivered by the sensor indicates when the screen turns brighter or darker. Used in combination with StimTrak, a trigger is generated when the amount of light is higher than the (customizable) threshold, which means that the exact onset of any visual stimulus can be marked. It can easily be attached to any screen with double-sided adhesive washers and connects to the auxiliary input of the amplifier.

Respiration Belt

The Respiration Belt measures the thoracic or abdominal respiratory movements and converts them into electrical voltage. It consists of an elastic belt with a pouch, a pneumatic sensor, a transducer and a cable for the connection to the amplifiers’ auxiliary ports.

Temperature Sensor

The Temperature Sensor measures ambient or skin temperatures. Due to its very little size and weight it reacts very fast to temperature changes. For the recording of skin temperature it should be attached directly to the skin using an adhesive tape.

BIP2AUX adapter

The BIP2AUX adapter is a tiny, analogue differential DC amplifier that allows you to record bioelectrical signals with a bipolar montage (ExG signals, like EOG, ECG or EMG). The BIP2AUX adapter connects to your EEG amplifier’s AUX input and turns it into an even more versatile research tool.
